2. The system for dynamic selection of transmission resources according to claim 1 , wherein the base station is further configured to increment the first counter of the base station corresponding to the selected certain transmission resource when a signal level on the selected certain transmission resource is less than a predetermined threshold, and otherwise not increment the first counter of the base station.
3. The system for dynamic selection of transmission resources according to claim 2 , wherein the base station and the mobile terminal are each configured to estimate the transmission quality index of the selected certain transmission resource as the state of the particular first counter of the base station and the state of the first counter of the mobile terminal corresponding to the selected certain transmission resource.
4. The system for dynamic selection of transmission resources according to claim 2 , wherein the base station and the mobile terminal are each configured to estimate the transmission qualify index of the selected certain transmission resource from a prediction function having the state of the first counter of the base station and the state of the first counter of the mobile, terminal corresponding to the selected certain transmission resource as predictive variables, the prediction function being identical for the base station and for the mobile terminal.
5. The system for dynamic selection of transmission resources according to claim 1 , wherein each of the base station and the mobile terminal has at least one second counter associated with the each transmission resource of the plurality of transmission resources, the transmission quality index of the selected certain transmission resource being estimated at the base station and at the mobile terminal from a prediction function having the state of the first counter of the base station the state of the first counter of the mobile terminal, a state of a second counter of the base station, and a state of a second counter of the mobile terminal, as predictive variables.
6. The system for dynamic selection of transmission resources according to claim 5 , wherein: when the base station determines that the selected certain transmission resource is not available, the base station is configured to increment the second counter of the base station corresponding to the selected certain transmission resource; when the mobile terminal determines that the beacon signal is not present on the selected certain transmission resource, the mobile terminal is configured to increment the second counter of the mobile terminal corresponding to the selected certain transmission resource.
7. The system for dynamic selection of transmission resources according to claim 6 , wherein the base station and the mobile terminal are each configured to calculate the transmission quality index of the selected certain transmission resource as C 1 C 1 + C 2 which C 1 is the state of the first counter of the base station and the state of the first counter of the mobile terminal corresponding to the selected certain transmission resource, and C 2 is the state of the second counter of the base station and the state of the second counter of the mobile terminal corresponding to the selected certain transmission resource.
8. The system for dynamic selection of transmission resources according to claim 6 , wherein the base station and the mobile terminal are each configured to calculate the transmission quality index of the selected certain transmission resource as C 1 C 1 + C 2 + α log t C 1 + C 2 in which C 1 is the state of the first counter of the base station and the state of the first counter of the mobile terminal and C 2 is the state of the second counter of the base station and the state of the second counter of the mobile, terminal corresponding to the selected certain transmission resource, α is a positive parameter, and t is a temporal index incremented at each superframe.
9. The system for dynamic selection of transmission resources according to claim 1 , wherein when the base station or the mobile terminal determine that an error rate on the selected certain transmission resource is higher than a predetermined threshold value, the base station or the mobile terminal is configured to increment a particular second counter associated with the selected certain transmission resource.
10. The system for dynamic selection of transmission resources according to claim 9 , wherein the base station and the mobile terminal are each configured to calculate the transmission quality index of the selected certain transmission resource as C 1 C 1 + C ′ 2 in which C 1 is the state of the first counter of the base station and the state of the first counter of the mobile terminal corresponding to the selected certain transmission resource and C′ 2 is a state of a second counter of the base station and a slate of a second counter of the mobile terminal corresponding to the selected certain transmission resource.
